What affects the price

Replacing your roof involves several variables that shift your final bill. The total square footage of your property is the biggest factor, followed closely by the pitch or steepness of your roof, which dictates how safely crews can work. You will also need to choose your materials—architectural shingles, metal, or tile each carry different price points. We also have to account for the removal and disposal of your current roof, plus the condition of the underlying wood decking that might need repairs once the old shingles are off. Exact pricing confirmed free on the call.
